Self esteem and confidence completely gone

Before pregnancy I could eat or drink whatever I wanted and never gained an ounce. (I was that lucky bit*h). I was always around 120 pounds. Now at 19 weeks I’m almost 140... this is the most I’ve ever weighed. Boobs, butt, and belly are all rounder. I try to dress in a way to hide my belly but I’m pregnant so it obviously shows. My husband and I haven’t had sex in probably 8 weeks and last night he refused me for the 4th time in a row. I asked him if he’s turned off by my belly and he just told me to go to sleep. And I know it will only get bigger... and he will only become more turned off by me. It’s a horrible feeling. And it’s really not fair considering he himself is over 300 pounds and has a huge belly 😔
